What are the tinting techniques for powder coatings?

1.
What is color

Color is a kind of visual angle nerve sensation caused when the human eye is stimulated by a certain wavelength and intensity of radiant energy.
Although the colors are very different, the most basic colors are only three basic colors: red, yellow, and blue, which are usually called the three primary colors.
The two primary colors are mixed with each other in equal amounts to form a secondary color (intermediate color), and the secondary color and the primary color are mixed with each other in equal amounts to become a multi-color com" href="">coating online coatingol.

Pigments are usually determined by the three parameters of hue, saturation, and lightness, which are also called the three elements of color.

A single color does not add other colors to become a pure color, and other colors are added to become intermediate colors or multiple colors.
When two coated objects with the same hue are illuminated by different lights or sunlight, the two objects show different colors and shades.
This is the nature of brightness.
The color of a certain hue has strengths and weaknesses, which is saturation The difference in degree.

Color formula

 Generally this kind of powder coatings are mainly inorganic pigments, which have better color durability and lower cost.
Inorganic coatings have brighter colors, higher tinting power, and higher cost.
, According to the cost, the light resistance of the paint also has a grade, but the price will be expensive.
According to the vividness of the color sample, the standard formula can be debugged.

Toning skills of powder coatings

Pigments used in powder coatings can usually be classified according to different methods such as production methods, composition and structure, and functions.

1.
Classification of pigments according to production methods

The production method can be divided into natural pigments and synthetic pigments.
Generally less natural pigments are used in powder coatings.
The synthetic pigments include titanium dioxide, iron oxide series, phthalocyanine series, azo, polycyclic pigments and so on.

2.
Functional distinction

According to its function in powder coatings, it can be divided into coloring pigments, extender pigments (also called fillers), anti-rust pigments, conductive pigments, etc.
For most functional powder coatings, the application of functional fillers is very important.

3.
Hue in the toning process of powder coatings

The pigments used in powder coatings show different hues due to different factors such as the chemical composition, crystal structure, surface state, particle size, process and equipment of the pigments.
For example, carbon black is the most widely used pigment in powder coatings.
When the particle size decreases or the surface increases, the blackness of carbon black will increase, the absorption of light will be more, and the reflection will be less, making people feel darker.

It is very important to understand the color relative to the toning of powder coatings.
For example, if the adjustment is exactly the same as the model, it is set to 10 (which means that you are very satisfied, and you don't need to add any more colorants).
Then the process from 0 to 9 is relatively easy to accomplish, and the process from 9-10 is very difficult to complete.

The gorgeousness of the color sample

Inorganic pigments generally have good gloss and color retention and low cost, but the pigments are darker (that is, not bright) and have low coloring power, while organic pigments are the opposite.
Of course, some large-scale organic pigments have lightfastness above level 7 (lightfastness 1-8, level 8 is the highest level), weather resistance is above level 4 (weatherability 1-5, level 5 is the highest level), but the price is extremely high.

 Because the entire structure, chemical composition and form of the pigment are different, the hue that it finally appears in front of people is also different.

At the end, no paint is needed, only hue is missing.
